我正在按父类别ID显示子类别列表,并希望显示类别图像以代替类别名称

这是我到目前为止所拥有的

<div id="menu_brands">
<div class="brand_head">
    <h3><?php echo $this->__('Browse By Brand') ?></h3>
</div>
<div class="brand_list">
    <?php
        $cats = Mage::getModel('catalog/category')->load(6)->getChildren();
        $catIds = explode(',',$cats);

        $categories = array();
            foreach($catIds as $catId) {
                $category = Mage::getModel('catalog/category')->load($catId); 
                $categories[$category->getName()] = $category->getUrl();
                $img = $category->getImageUrl(); //I suspect this line is wrong
        }

        ksort($categories, SORT_STRING);
    ?>

        <ul>
            <?php foreach($categories as $name => $url): ?>
                <li>
                    <!--<a href="<?php echo $url; ?>"><?php echo $name; ?></a>-->
                    <a href="<?php echo $url; ?>" title="<?php echo $name; ?>">
                        <img src="<?php echo $img; ?>" width="auto" alt="<?php echo $name; ?>" /> <!--I suspect this line is wrong-->
                    </a>
                </li>
            <?php endforeach; ?>
        </ul>
</div>
</div>

我已经尝试了无数种方法来显示图片来代替类别名称,但似乎没有任何方法可以让图片出现。目前,上面的输出是一个空的“img src”,因此我正在尝试的显然是一个错误(可能是实现我所追求的更好的方法)

请有人指出是什么问题吗

如果它有任何相关性,我打算以后做的是以网格格式显示类别图像(每行3或4个)


非常感谢。

请尝试使用此方法,而不要使用
$img=$category->getImageUrl()
$img=getCategoryImage($category)


(现已失效)参考:

我们自己设法解决了这个问题-请参阅下面的修复

<?php
    //gets all sub categories of parent category 'Brands'
    $cats = Mage::getModel('catalog/category')->load(6)->getChildren();
    $catIds = explode(',',$cats);

    $categories = array();
    foreach($catIds as $catId) {
        $category = Mage::getModel('catalog/category')->load($catId); 
        $categories[$category->getName()] = array(
            'url' => $category->getUrl(),
            'img' => $category->getImageUrl()
        );
    }

    ksort($categories, SORT_STRING);
?>
    <ul>
        <?php foreach($categories as $name => $data): ?>
            <li>
                <a href="<?php echo $data['url']; ?>" title="<?php echo $name; ?>">
                    <img class="cat-image" src="<?php echo $data['img']; ?>" />
                </a>
            </li>   
        <?php endforeach; ?>
    </ul>


令人惊讶的是,我们没有得到更多的支持,因为这是一个相对简单的Magento问题。不过,感谢B00MER的回答。

zigojacko的解决方案并不理想,因为它在循环中单独加载模型。这并不能很好地扩展,而且有许多类别会影响数据库。理想情况下,您应该将图像添加到子集合中

更快的解决方案是将图像属性添加到具有ID筛选器(如B00MER)的集合中:
// Gets all sub categories of parent category 'Brands'
$parent = Mage::getModel('catalog/category')->load(6);

// Create category collection for children
$childrenCollection = $parent->getCollection();
// Only get child categories of parent cat
$childrenCollection->addIdFilter($parent->getChildren());
// Only get active categories
$childrenCollection->addAttributeToFilter('is_active', 1);

// Add base attributes
$childrenCollection->addAttributeToSelect('url_key')
        ->addAttributeToSelect('name')
        ->addAttributeToSelect('all_children')
        ->addAttributeToSelect('is_anchor')
        ->setOrder('position', Varien_Db_Select::SQL_ASC)
        ->joinUrlRewrite();

// ADD IMAGE ATTRIBUTE
$childrenCollection->addAttributeToSelect('image');

?>
<ul>
    <?php foreach($childrenCollection as $cat): ?>
        <li>
            <a href="<?php echo $cat->getURL(); ?>" title="<?php echo $cat->getName(); ?>">
                <img class="cat-image" src="<?php echo $cat->getImageUrl(); ?>" />
            </a>
        </li>   
    <?php endforeach; ?>
</ul>
//获取父类别“品牌”的所有子类别
$parent=Mage::getModel('catalog/category')->load(6);
//为儿童创建类别集合
$childrenCollection=$parent->getCollection();
//仅获取父猫的子类别
$childrenCollection->addIdFilter($parent->getChildren());
//仅获取活动类别
$childrenCollection->addAttributeToFilter('is_active',1);
//添加基本属性
$childrenCollection->addAttributeToSelect('url\u key')
->addAttributeToSelect('名称')
->addAttributeToSelect(“所有子项”)
->addAttributeToSelect('is_anchor')
->setOrder('position',Varien\u Db\u Select::SQL\u ASC)
->joinUrlRewrite();
//添加图像属性
$childrenCollection->addAttributeToSelect('image');
?>

致命错误:调用第49行“$img=getCategoryImage($category);”中//路径//中未定义的函数getCategoryImage()(第49行)函数是否应该在同一个文件中声明?目前,它们与所有其他文件一起位于相关的extensions Navigation.php中。谢谢谢谢罗伯特,这个比较优雅。这个很好用,谢谢罗伯特!对于任何想要获取缩略图而不是类别的人,请使用
$childrenCollection->addAttributeToSelect(“缩略图”)
然后在
foreach
// Gets all sub categories of parent category 'Brands'
$parent = Mage::getModel('catalog/category')->load(6);

// Create category collection for children
$childrenCollection = $parent->getCollection();
// Only get child categories of parent cat
$childrenCollection->addIdFilter($parent->getChildren());
// Only get active categories
$childrenCollection->addAttributeToFilter('is_active', 1);

// Add base attributes
$childrenCollection->addAttributeToSelect('url_key')
        ->addAttributeToSelect('name')
        ->addAttributeToSelect('all_children')
        ->addAttributeToSelect('is_anchor')
        ->setOrder('position', Varien_Db_Select::SQL_ASC)
        ->joinUrlRewrite();

// ADD IMAGE ATTRIBUTE
$childrenCollection->addAttributeToSelect('image');

?>
<ul>
    <?php foreach($childrenCollection as $cat): ?>
        <li>
            <a href="<?php echo $cat->getURL(); ?>" title="<?php echo $cat->getName(); ?>">
                <img class="cat-image" src="<?php echo $cat->getImageUrl(); ?>" />
            </a>
        </li>   
    <?php endforeach; ?>
</ul>
